Product Introduction
Ladder lock: the buckle body has multiple webbing slots and two crossbars, and the lower end is connected to a round-head pull tab; the overall shape is a relatively narrow, waisted profile. The webbing is threaded through the webbing slots and back through the crossbars to adjust the length of the shoulder strap or fixing strap; the pull tab at the lower end serves as the operating point, and the specific webbing path is confirmed according to the structure.
DAWEI provides plastic buckle injection molding and mold development services, supporting evaluation based on drawings and samples, prototyping and bulk supply. Size, material, color and markings can be customized per project; the installation fit between the buckle body and the webbing, the adjustment feel and the connection performance are confirmed with matching samples.

- Material Selection
- Thermoplastic materials such as POM / PA can be evaluated based on the rigidity of the crossbar or loop body, the molded appearance, and the operating environment. Specific material grades, surface finishes, and colors can be customized per project, and the actual material selection is confirmed against samples and matching requirements.
- Molding Process
- The outer frame, webbing slots, crossbars, and lower pull tab can be formed by injection molding, with the mold designed for dual crossbars, a narrow-profile contour, and a round-head pull tab. During sampling, check the opening edges, webbing passage, and adjustment performance after back-threading.
- Customization Options
- Customizable options include dual crossbars, a narrow-profile contour, and a round-head pull tab, as well as buckle body dimensions, thickness, material, color, and LOGO artwork. Compatible webbing width, thickness, number of back-threading layers, and installation position can be evaluated per project. Aperture and connection fit must be confirmed with the actual webbing and other matching components.
- Applications
- It can be used for strap length adjustment and management at locations such as backpack shoulder strap adjustment, bag compression straps, and storage bag fixing straps, and the installation plan should be confirmed based on webbing routing, the anchor end, and the usage conditions.
Uses and Applications
Backpack shoulder strap adjustment
The shoulder strap length is managed via the webbing slots and crossbars; the narrow-profile dual-crossbar round-head pull tab can be designed according to the operating position.
Bag compression strap
Used for side or external adjustment straps on bags; the contact effect between the crossbar texture and the actual webbing needs verification.
Storage bag securing strap
Used for organizing the length of fixed straps; the threading path, pull tab direction, and fixed end are matched to the bag structure.
